三臺主機分別部署LAMP

三臺主機分別部署LAMP

 要求：httpd, php, mariadb分別部署在一個單獨的主機上，一個虛擬主機提供phpMyAdmin，另一個虛擬主機提供wordpress，為phpMyAdmim提供https服務；

一． 分工三臺主機

A  httpd主機   172.16.35.1

B  php-fpm主機 172.16.35.2

C  mariadb主機 172.16.35.3

為方便實驗在這里關閉防火墻

#iptables-F

#setenforce0

安裝所需rpm包：

在A上yum -y install httpd，B主機yum -y install php-fpm， C上yum -y install mariade-server php-mysql

二． httpd主機設置

1.設置vhost1.conf和vhost2.conf

[root@zq~]# vim /etc/httpd/conf.d/vhost1.conf

<VirtualHost172.16.35.1:80>

ServerNamewww1.test.com

DocumentRoot"/data/vhost/www1"

ProxyRequestson

DirectoryIndexindex.php

ProxyPassMatch^/(.*\.php)$ fcgi://172.16.35.2:9000/data/vhost/www1/$1 動態資源代理轉發給第2臺主機

<Directory"/data/vhost/www1">

OptionsNone

AllowOverrideNone

Requireall granted

</Directory>

</VirtualHost>

[root@zq~]# vim /etc/httpd/conf.d/vhost2.conf

<VirtualHost172.16.35.1:80>

ServerNamewww2.test.com

DocumentRoot"/data/vhost/www2"

ProxyRequestson

DirectoryIndexindex.php

ProxyPassMatch^/(.*\.php)$ fcgi://172.16.35.2:9000/data/vhost/www2/$1 動態資源代理轉發給第2臺主機

<Directory"/data/vhost/www2">

OptionsNone

AllowOverrideNone

Requireall granted

</Directory>

</VirtualHost>

2.修改配置文件指定NDS以及域名解析

[root@zq~]# vim /etc/resolv.conf

#Generated by NetworkManager

DNS=172.16.35.1

nameserver172.16.0.1

#本地域名解析

[root@zq ~]#vim /etc/hosts

127.0.0.1localhost localhost.localdomain localhost4 localhost4.localdomain4

::1localhost localhost.localdomain localhost6 localhost6.localdomain6

172.16.35.1www1.test.com www2.test.com

3.創建靜態默認文件：

[root@zq~]# mkdir -p /data/vhost/www{1,2}

[root@zq~]# vim /data/vhost/www1/index.html

<h2>zq1第1臺物理機靜態數據 172.16.35.1</h2>

[root@zq~]# vim /data/vhost/www2/index.html

<h2>zq2第1臺物理機靜態數據 172.16.35.1</h2>

4.然后測試本機靜態數據是否可以正常訪問

================================================================

三．php-fpm主機：

1.修改配置文件

[root@zq~]# vim /etc/php-fpm.d/www.conf

listen = 172.16.35.2:9000監聽本機地址端口

listen.allowed_clients= 172.16.35.1 允許A主機連接

2.創建資源映射目錄及文件

mkdir -pv/data/vhost/www{1,2}

[root@zq~]# vim /data/vhost/www1/index.php

<h2>第2臺物理機a</h2>

<?php

$conn =mysql_connect('172.16.35.3','testuser','testpass');

if($conn)

echo"OK";

else

echo"Failure";

phpinfo();

?>

[root@zq~]# vim /data/vhost/www2/index.php

<h2>第2臺物理機b</h2>

<?php

$conn =mysql_connect('172.16.35.3','testuser','testpass');

if($conn)

echo"OK";

else

echo"Failure";

phpinfo();

?>

3.安裝加速器php-xcache

yum -yinstall php-xcache

解壓wordpress以及php-myadmin分別在www1和www2中

4.修改wordpress的配置文件

[root@zq~]# cd /data/vhost/www1/wordpress/

[root@zq wordpress]# ln -s wp-config-sample.phpwp-config.php

[root@zq wordpress]# vim wp-config.php

// **MySQL 設置 - 具體信息來自您正在使用的主機 ** //

/**WordPress數據庫的名稱 */

define('DB_NAME','qqdb');

/** MySQL數據庫用戶名 */

define('DB_USER','qquser');

/** MySQL數據庫密碼 */

define('DB_PASSWORD',qqpass');

/** MySQL主機 */

define('DB_HOST','172.16.35.3'); 這里的地址是指向第C主機的數據庫地址

/** 創建數據表時默認的文字編碼 */

define('DB_CHARSET','utf8');

/** 數據庫整理類型。如不確定請勿更改 */

define('DB_COLLATE','');

5.修改phpMyAdmin的配置文件

[root@zqt ~]# ln -s /data/vhost/www2/phpMyAdmin-4.4.14.1-all-languages/data/vhost/www2/myadmin

[root@zq ~]# ln -s /data/vhost/www2/myadmin/config.sample.inc.php/data/vhost/www2/myadmin/config.inc.php

[root@zq ~]# vim /data/vhost/www2/myadmin/config.inc.php

$cfg['blowfish_secret']= '4pfPnDAJFPA4WMWaQxD'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

隨機碼用！r opensslrand -base64 15 生成用于通信加密

/*

* Serversconfiguration

*/

$i = 0;

/*

* Firstserver

*/

$i++;

/*Authentication type */

$cfg['Servers'][$i]['auth_type']= 'cookie';

/* Serverparameters */

$cfg['Servers'][$i]['host']= '172.16.35.3'; $cfg['Servers'][$i]['connect_type'] = 'tcp';

$cfg['Servers'][$i]['compress']= false;

$cfg['Servers'][$i]['AllowNoPassword']= false;

四.mariadb主機

1.啟動被查看數據庫且設定其為開機啟動

systemctlstart mariadb.service

systemctlstatus mariadb.service

systemctlenabled mariadb.service

2.授權創建用戶

[root@zq ~]#mysql

mysql>GRANT ALL ON qqdb.* TO 'qquser'@'172.16.%.%' IDENTIFIED BY 'qqpass';

mysql>FLUSH PRIVILEGES;

mysql>CREATE DATABASE qqdb；

=====================================================================================

五．測試php是否可以連接數據庫

http://www1.test.com/測試A主機的靜態數據

http://www2.test.com/第1臺主機的靜態數據連接成功

http://www1.test.com/index.php第2臺物理機的第一個虛擬主機的動態數據訪問成功

http://www2.test.com/index.php第2臺物理機的第二個虛擬主機的動態數據訪問成功

http://www1.test.com/wordpress/index.php測試轉發第2臺主機第一個虛擬主機

http://www2.test.com/myadmin/index.php測試轉發第2臺主機第二個虛擬主機

六．給B主機上的php-myadmin提供https服務，詳情參考單主機部署LAMP

七．壓力測試

1.httpd主機的靜態數據測試html：

4.動態測試myadmin數據

[root@zq~]# ab -c 100 -n 1000 http://www2.test.com/data/vhost/www2/myadmin/index.php

DocumentPath: /data/vhost/www2/myadmin/index.php

Time perrequest: 0.490 [ms] (mean, across all concurrent requests)

Transferrate: 486.59 [Kbytes/sec] received

注意對于bash來書單次接受的數據不能大于10024所以壓力測試時不能把數值調的過大

5.表格：

所以用三臺主機的話動態數據的響應速度會大大提高
